Script using a variable for wait_template

hi @petro, i’m getting error Message malformed: invalid template (TemplateAssertionError: No test named 'None'.) for dictionary value @ data['sequence'][0]['value_template']

what does that mean?

it means I made a typo. Replace the work None with none.

@limawaken

whats the difference doing

announcement_msg: '{{ ("1","2","3") | random }}'

and

announcement_msg: >
    {{ ("1","2","3") | random }}

?

the > means “Multiline field” in yaml. All lines below it are part of the field with the arrow (until the next field). Read up on it here.

PSA: Template and yaml

Templates are indicated by lines that start and end with {% %} or {{ }}. Everything else is yaml. The language contained inside {% %} and {{ }} is Jinja, it is not yaml.

@limawaken

is it when using > then i don’t need to enclose the template with ''?

for the condition value template you used "" instead of the single ''. when do we use one or the other?

@limawaken

i also noticed (not here, but elsewhere) sometimes there is a - after the > like so:

  announcement_msg: >-
    {{ ("1","2","3") | random }}

when would i need to use the >-?

the - removes leading whitespace. It’s literally pointless in the home assistant world because we trim leading and trailing whitespace.
